Let us C programmes Solutions

(a) Write down macro definitions for the following: 1. To test whether a character entered is a small case letter or not. 2. To test whether a character entered is a upper case letter or not. 3. To test whether a character is an alphabet or not. Make use of the macros you defined in (1) and (2) above. 4. To obtain the bigger of two numbers. // Let Us C (Chapter 7 : The C Preprocessor) : Program-1 /* Write down macro definitions for the following: 1.
